I'm using a mysql database and connecting my vb.net program to the DB over a
network connection. i would like to bring this data over to a vb.net random
access file. does anyone know how to convert my DB into a binary file? and
how to convert my code to use a file instead of the db?

Hi,
If you store the data in random access file you will lose the
ability to query the data. I think it might be better to install a copy of
mysql on your local machine and making a local copy of the database to work
with. My Sql is open source and can be downloaded from dev.mysql.com.
Another option is move the database to sql express which is also free from
microsoft.

Is there any way to hold data, and do queries on it, but make it file based,
so the data can be transported w/ the program?
Hi,
You have a couple of options here. First you could move the data
to an access database. Access is a file based database which does not
require any database server to be installed.
Sql express is a free version of sql server 2005 which will allow
you to attached a database file to the server. The computer running the
application is required to have sql express installed. http://msdn.microsoft.com/sql/expres...lexcustapp.asp
LINQ is a preview to a new techology to be offered in the next
version of visual basic which will allow you to query classes. You could
create a class which contains all the data in the database and store it in a
file. Understand this is a early beta and there is no guarantee that code
you write now will still work when LINQ is released. Here is a link to info
on LINQ. (I recommend you install betas on virtual pc or virtual server) http://msdn.microsoft.com/netframework/future/linq/

What would give better performance, serializing a multidimensional array
and storing it in a single entry in a table or storing each element of
the array in a separate table and associating the entries with the entry
in the other table?
Having a separate table would result in two queries instead of one, but
you wouldn't have to deal with the overhead of serializing and
unserializing data.

Hi,
is it possible that due to OS crash or mysql itself crash or some e.g.
SCSI failure to lose all the data stored in the table (let's say million
of 1KB rows). In other words what is the worst case scenario for MyISAM
backend?
Also is it possible to not to lose data but get them corrupted?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
